How Many Stalls Do I Need for My Event?
Four stalls is the middle ground between a 2 stall restroom trailer and an 8 stall restroom trailer. It works well for guest counts in the low hundreds, whether that is a backyard wedding reception or a two-day build crew rotation. If you're not sure where your event lands, the how many porta potties do I need guide walks through headcount math, and the general restroom trailer rental page covers unit sizes side by side. Construction crews in Great Falls sizing up sanitation for a multi-week job should also check OSHA portable toilet requirements, since OSHA 1926.51(c)(1) sets toilet ratios by crew size, not by trailer style. For events without heavy labor rotation, a standard porta potty rental or a deluxe flushable porta potty can supplement a 4 stall unit at the edges of a site, keeping the trailer itself reserved for the main crowd flow.
What Does a 4 Stall Restroom Trailer Cost in Great Falls?
Pricing depends on rental length and delivery distance. Here is what the range typically looks like:
| Duration | Typical Price |
|---|---|
| Day | around $800 |
| Week | around $1,397 to $1,650 |
| Weekend | around $2,000 |
| Event (multi-day) | $2,499 to $3,899 |
Delivery adds a separate fee, generally between $100 and $172 depending on whether it's a single trip or a longer placement. For a deeper cost breakdown across trailer sizes, see restroom trailer rental cost or the general porta potty rental cost page. If your event runs closer to daily rentals instead of a week-long booking, porta potty rental per day has that pricing laid out too. Great Falls Porta Pros quotes delivery based on site access, and a roll-off style delivery truck needs about 60 feet of straight clearance behind it, so tight driveways or alley placements in older parts of Great Falls should be flagged when you book.
Is a 4 Stall Trailer ADA Accessible?
Ask before you book, since not every 4 stall trailer includes a wheelchair-accessible stall by default. Under ADA Standards section 213.2, when single-user portable units are clustered, at least 5 percent must be accessible, with a minimum of one unit regardless of cluster size. That standard applies more directly to grouped porta potties, but Great Falls Porta Pros builds accessible stalls into most 4 stall trailers on request, with a 60 inch turning circle per ADA Standards 304.3.1 and door hardware that meets the one-hand, 5-pound operable force limit in ADA Standards 309.4. If accessibility is a firm requirement for your venue, ask specifically and check the ADA accessible porta potty page or the broader ADA restroom requirements guide before your event date locks in.
Restroom trailers also need handwashing support nearby if food or drink service is part of your event. Under 29 CFR 1910.141(d)(2), a proper handwashing setup needs soap and a way to dry hands, not just sanitizer. A handwashing station rental or portable sink rental pairs well with a 4 stall trailer for weddings and fairs. Events in the Great Falls area sometimes also need temporary fence rental around the trailer footprint, especially at larger venues, and a light tower rental if the event runs into evening hours.
What size crowd does a 4 stall trailer handle?
A 4 stall unit comfortably serves 100 to 300 guests for a single-day event, less if it's a multi-day festival with continuous foot traffic. For crowds over 300, pair it with a 8 stall restroom trailer or add standard units at portable toilet rental.
How far in advance should I book?
Book at least 2 to 3 weeks out for weekend events, sooner during wedding season. Great Falls Porta Pros delivers throughout Great Falls and nearby communities like Black Eagle, 3.9 miles northeast, and Malmstrom AFB, 5.9 miles east. See request a quote to lock in a date.
Does the trailer need a power hookup?
Most 4 stall trailers run on internal power and don't need a hookup, but confirm at booking. If your site already has a generator or temporary power pole from a construction phase, mention it. Otherwise no hookup is needed for standard use.
Can I rent one for a home renovation project?
Yes, though a single-stall unit is often more practical and cheaper for a solo renovation crew. Check home renovation porta potty for sizing guidance suited to smaller residential jobs rather than event-scale trailers.
Is delivery available outside Great Falls city limits?
Yes. Great Falls Porta Pros serves outlying communities including Gibson Flats, 5.4 miles southeast, and Sand Coulee, 13.5 miles southeast. Delivery fees scale with distance, so ask for an exact quote through contact or check service areas.
